8.4 REPLACEMENT OF MAJOR PARTS
The system includes parts that need periodic replacement. The parts should be
replaced as scheduled. Use of parts over their service life can cause a system
failure.
• Turn off the main power source before replacing parts.
Otherwise, an electric shock or trouble may be caused.
• Two or more persons shall replace the liquid crystal
monitor. If only one person does this work, he may
drop the LCD, resulting in injury.
• Even after the main power source is turned off, some
high voltages remain for a while. Do not contact the
inverter circuit in the LCD with bare hands. Otherwise,
an electric shock may be caused.
